Bow legged knee due to waer and tear on the inner (medial) side of the knee
An X Ray of an Oxford Knee replacement

This patient had a Total knee replacement on one side and a Unicondylar knee replacement on the other. The X Ray at the left shows an Oxford Unicondylar knee replacement developed by Professor J.Goodfellow and colleagues at Oxford. The X Ray on the right is a Total knee replacement. It is obvious that the Oxford knee is half a Total knee replacement but it has the advantages of preserving the cruciate ligaments, and is a minimally invasive surgery. 

The Oxford knee replacement is suitable for roughly 30-40% patients who have wear and tear only on the inner half of the knee and in whom the bow legged deformity can be corrected by the Surgeon in the Outpatient clinic by applying pressure on the leg in the opposite direction.

The X Ray on the left is a picture of the bow legged knee taken with the patient standing. The X Ray on the right is a picture of the same patient taken with the leg held in a corrected position. It shows that the bow legged deformity is fully correctable and it also shows clear joint space on the outer side of the knee implying that the outer half of the knee is not worn out. 

It is vital that the outer half of the knee be normal and the anterior cruciate ligament is intact if the Oxford knee replacement is to give good results. 

Recovery from this operation is very quick and fit patients may be able to go home in as little as 2-3 days after surgery. Blood loss is very less and consequently blood transfusion is not needed. The range of movements is nearly full and the knee feels more stable as the ligaments have been preserved.
